BOQ vs Estimate: Understanding the Difference for Saudi Construction Projects

In Saudi construction, the terms 'BOQ' and 'estimate' are sometimes used interchangeably, but they have important distinctions. Understanding the difference helps construction professionals choose the right approach for their project stage and purpose.

What Is a Construction Estimate?

An estimate is an approximate calculation of project costs, typically prepared in the early stages of project planning when detailed drawings may not yet be available. Estimates use square meter rates, benchmark costs, or historical project data to provide a ballpark figure for budgeting purposes.

What Is a BOQ?

A BOQ is a detailed, itemized list of every material, labor item, and cost element in a construction project, prepared from completed design drawings. Unlike an estimate, a BOQ is precise and forms the basis for competitive tender pricing and procurement.

When to Use Each

Use an estimate during project feasibility and early planning stages to assess if the project is financially viable. Switch to a detailed BOQ once design is complete and you need accurate quantities for procurement and contractor tendering. Benna KSA's AI BOQ tool bridges this gap by generating reasonably accurate BOQs even before final design completion.
